Learn the language with the fluent you. Your language isn't growing for one reason. You don't speak enough. And the real block isn't vocabulary. It's that pulling your own thoughts out of your head has never been trained. Not reciting memorized lines, but saying what you actually think, in your own words. That's where conversation starts. Speak, get your grammar and phrasing corrected, repeat daily. nawana is built for exactly that. Sixty seconds of recording builds your fluent future self. Not a native speaker, not a voice from a movie. A goal you can actually reach. Your own voice, fluent. Pitch, tone, and pace stay yours. The only thing that changes is the language. HOW IT WORKS Conversations start from your interests, one tap, like placing a call Talk with the fluent future you. Stumble freely, every turn comes back fluent Hang up, and your expressions, words, and grammar are analyzed into your own textbook Every word you say out loud checks itself off in your wordbook Your level is measured, only from what you actually said TALK. It makes you speak, then finds what to fix Call daily about free topics, situations you actually face, or news matched to your interests. Every session ends in a scorecard across five skills (vocabulary, grammar, expressiveness, fluency, pronunciation) and every fumbled line becomes a review card automatically. WATCH. See tomorrow's conversation today An interview, a doctor's visit, an awkward ask. Describe the situation in one line and your fluent self lives it first. Your lines play in your own fluent voice, and any sentence you want is one tap away from shadowing. SHADOW. Until it comes out on its own The voice you match is your own. Speak along with the fluent line, loop the hard part at 0.5x, and see a per-word verdict: nailed, swapped, or skipped. SPEECH. Say it out loud before the day it counts Read a script aloud from a prompter that follows your voice. Turn the camera on and you keep a vertical video of you and your script together. Every take is scored for accuracy, pace, pauses and filler words, and a coach tells you what to try next. Anyone can practice the built-in script; writing one with AI or adding your own talk comes with Plus and Max. REVIEW. It returns right before you forget Fumbled sentences come back as spaced-repetition drills, answered out loud, never multiple choice. A pool of about 8,000 CEFR-graded words sits underneath, and every word you use is ticked off automatically. YOUR VOICE, TREATED CAREFULLY Recording is sixty seconds at setup, once. Nothing is ever recorded outside a conversation you started. Re-record or delete your voice anytime. Sessions, drills, and progress stay on your iPhone. SUBSCRIPTION Light gives you 150 minutes of talk a month, Plus 600 and Max 1,200. A new Watch scene uses 5 of those minutes, and watching one again is free. Plus and Max also let you write Speech scripts with AI or add your own. Spend the minutes in one go or across the month, and if you need more, you can buy 50 extra minutes, with or without a plan. Review, replay, and building situations are always free. Sixty seconds of setup. Start your first call with the fluent future you today.
